The present application claims priority benefit from U.S. Provisional Patent Application No. 62/079,310, entitled “BURNER OR BOILER ELECTRICAL DISCHARGE CONTROL”, filed Nov. 13, 2014, co-pending at the time of filing, (docket number 2651-260-02); which, to the extent not inconsistent with the description herein, is incorporated by reference.

BACKGROUND

Applying a voltage, charge, and/or electric field into a combustion zone may improve the control of flame shape and heat transfer. Moreover, this technique can also be used to optimize the complex chemical reactions that occur during combustion, minimizing harmful emissions, while also maximizing system efficiency.

A combustion system may include one or more electrodes configured to apply a voltage, charge, and/or electric field to a flame. This combustion system may be connected to ancillary equipment such as computers, thermocouples, burning management equipment, and the like. However, the charged flame may contact different regions of the combustion system, discharging high voltages to ancillary equipment and ground. This high voltage discharge may damage ancillary equipment.

SUMMARY

A combustion system applies a charge, voltage, and/or electric field to a flame to improve combustion efficiency, emissions, and/or to control flame characteristics. The combustion system is operatively coupled to ancillary burner equipment that supports the application of a charge, voltage, and/or electric field to a flame, support control and measurement of flame characteristics, control pollutant output, control fuel delivery, control air delivery, and/or control flue gas delivery to the flame. To avoid unwanted high voltage discharges through the combustion system that can damage ancillary equipment or operational personnel, electrical isolation or an insulating material is placed between burner and flame, preventing the charging of the combustion chamber through burner, according to an embodiment.

In other embodiments, a safety insulation sub-system is employed as a power supply for ancillary burner equipment. Safety insulation sub-system includes a circuit of batteries that apply power to ancillary equipment.

In another embodiment, safety insulation sub-system includes a motor-generator power conversion system, whereby a motor drives a generator through a non-conductive transfer structure that avoids electrical discharges to ground. Motor can be replaced by another suitable mechanical power supply mechanism such as gasoline engine, steam turbine, compressed air turbine, and the like.

According to various embodiments, retrofitting is enabled since there is no necessity to build new equipment to accomplish effective discharge prevention in a combustion system.

DETAILED DESCRIPTION

Disclosed herein are embodiments of different approaches to insulate ancillary burner equipment from high voltage discharges. The present disclosure is hereby described in detail with reference to embodiments illustrated in the drawings, which form a part hereof. In the drawings, which are not necessarily to scale or to proportion, similar symbols typically identify similar components, unless context dictates otherwise. Other embodiments may be used and/or other changes may be made without departing from the spirit or scope of the present disclosure. The illustrative embodiments described in the detailed description are not meant to be limiting of the subject matter presented herein.

As used herein, “ancillary burner equipment” may refer to an apparatus employed in a combustion system to support the generation and control of a flame.

As used herein, “electrical insulation material” may refer to a material, which does not conduct electric current.

As used herein, “refractory material” may refer to a material, which may withstand high temperatures and may provide electrical insulation.

FIG. 1 depicts an embodiment of a combustion system 100. The combustion system 100 includes a burner 102 configured to provide fuel and air for the generation of a flame 108; an electrode 104 and an electrode 106 configured to apply a voltage, charge, and/or electric field to the flame 108; and a grounded combustion chamber 110 where combustion reactions can take place, according to an embodiment.

The burner 102 can be supported by ancillary equipment 112. In an embodiment, ancillary equipment 112 can include a blower, which can provide air to the burner 102 through an air inlet line 114. The ancillary equipment 112 can be connected to a suitable power supply. Other ancillary equipment 112 can include control equipment, burning management equipment, programmable logic controllers, computers, and/or thermocouples, among others.

A charge, voltage, and/or electric field can be applied to the flame 108 using a variety of electrode configurations, depending on the application. In an embodiment, the electrode 104 can go through a suitable aperture in a region of the combustion chamber 110, thus avoiding direct contact with the combustion chamber 110. The electrode 106 can enter the combustion chamber 110 through the burner 102. The electrode 106 can be coated with an insulation material 116 such as dielectric ceramic, refractory and the like; or may alternatively be supported with a dielectric gap between the electrode 106 and portions of the burner 102 held at a different electrical potential.

The electrode 104 and the electrode 106 can be connected to an amplifier, which can be fed by a power source 118 for charging the electrode 104 and the electrode 106 with AC or DC voltage. In addition, the power source 118 can be managed by a programmable controller.

If the burner 102 is charged by the flame 108, an electrical discharge can flow through the ancillary equipment 112 and ground, damaging ancillary equipment 112 and possibly representing a potential hazard to operational personnel. As a result, an electrical insulator can be placed between the burner 102 and the flame 108 to prevent the burner 102 from being charged when a voltage, charge, and/or electric field is applied to the flame 108. According to an embodiment, a non-conductive gasket 120 can be employed as electrical insulator between the burner 102 and the flame 108. Suitable materials for the non-conductive gasket 120 can include neoprene, polyether ether ketone (PEEK), Viton fluoroelastomer, polytetrafluoroethylene (PTFE), polyethylene, fiberglass, and/or fiberglass-reinforced plastic, among others.

Moreover, to prevent contact between the interior walls of the combustion chamber 110 and the flame 108, the combustion chamber 110 can be coated with an electrically insulating refractory material 122. Suitable refractory materials 122 can include aluminum oxides, silicon oxides and/or magnesium oxides.

In applications where refractory materials 122 cannot be used, different configurations of electrodes can be employed to prevent the flame 108 from contacting the internal walls of the combustion chamber 110. For example, one or more electrodes can be properly attached to an interior wall of the combustion chamber 110 so that if the flame 108 is charged positively, then electrodes can also be charged positively to repel the flame 108.

FIG. 2 illustrates an embodiment of a combustion system 200, where ancillary equipment 112 can be connected to a safety insulation sub-system 202 which can supply required power for operation, while also providing suitable electrical insulation to ancillary equipment 112. The safety insulation sub-system 202 can eliminate the path to ground of potential high voltage discharges from the charged flame. In some embodiments, a safety insulation sub-system 202 can be operatively coupled between the ancillary equipment 112 and ground, as shown in FIG. 2. In other embodiments, a safety insulation sub-system 202 can be operatively coupled between the power source 118 and the ancillary equipment 112. According to an embodiment, a safety insulation sub-system 202 can be made similarly to embodiments described in U.S. Pat. No. 4,580,063, incorporated by reference herein. According to another embodiment, a safety insulation sub-system 202 can be made similar to embodiments described in U.S. Pat. No. 4,442,364, incorporated by reference herein.

FIG. 3 illustrates a safety insulation sub-system 300, which represents an embodiment of the safety insulation sub-system 202. The safety insulation sub-system 300 can include a motor 302, a non-conductive transfer structure 304 and a floating generator 306. The motor 302 can be energized by a suitable AC power source 308, and can be connected to the generator 306 through the non-conductive transfer structure 304. As the motor 302 operates, the non-conductive transfer structure 304 can transfer mechanical energy to the generator 306. The generator 306 can convert this mechanical energy into electrical energy in the form of AC voltage at a current level suitable for operation of ancillary equipment 112.

The insulating properties of the non-conductive transfer structure 304 can eliminate electrical path to ground in the second safety insulation sub-system 300, protecting ancillary equipment 112 from potential high voltage discharges from the charged flame. In an embodiment, the non-conductive transfer structure 304 can include one or more non-conductive shafts 310 along with corresponding non-conductive couplings 312. In other embodiments, the non-conductive transfer structure 304 can employ magnetic couplings.

The motor 302 can be replaced by a suitable mechanical power supply mechanism, including internal combustion engines such as a gasoline engine. For example, the motor 302 can be replaced by a steam turbine, a compressed air turbine and the like.
